A variable diameter discharge system for controlling the flow and distribution of a material being fed into a bin. The variable diameter discharge system generally includes a storage bin including a bin opening for receiving a material to be stored in the storage bin. A hopper is suspended beneath the bin opening such that materials fed into the bin opening pass through the hopper. A ring member is connected to the hopper which includes a plurality of guide members adjustable between a first position and a second position. An opening is defined between the guide members; with the opening enlarging as the guide members are adjusted toward the second position. Springs connected between the guide members and the ring member bias the guide members toward the first position. The guide members move from the first position to the second position when a material is flowing through the opening.

A plastic article useful as a riser assembly for a septic tank or as part of another structure is comprised of a multiplicity of identical shape conical wall plastic risers. The risers are attached to each other at joints by tabs which engage rim segments; each end of the riser has alternating tabs and rim segments. A riser assembly wall undulates in the lengthwise direction. The risers nest within each other for shipment or storage.

An underwater energy storage system includes a tank for storing a compressed gas that is adapted to be stored underwater. The tank includes at least one water opening through which water from surrounding environment can flow into and out of the tank, and at least one gas opening through which the compressed gas is received. The underwater energy storage system further includes at least one duct communicating between the at least one opening for gas flow and a source of compressed gas and a compartment constructed over a roof of the tank, wherein said compartment is adapted for receiving weights at a sinking site of the tank.

The present invention discloses a cover device used to cover the built-in valve mounting channel port of IBC and a container. The IBC comprises a side plate, a base and a channel located in the base and used to receive the built-in valve. The cover device comprises a cover and structures or components used to detachably connect the cover to the side plate over the channel. The cover can be installed on the base at the position adjacent to the side plate, and can be rotated around a rotational axis of the cover itself, so as to open or cover the channel port. The cover is further provided with a lock hole, and the base is provided with a locking slot, so that the cover can be locked to the base by a disposable lock. The cover device of the present invention has a simple structure and is easy to operate. Further, it can well achieve the effect of dust-proof and/or thief-evident.

Adjustable storage systems, adjustable storage receptacles, and methods of manufacturing and using the same are disclosed. In one aspect, an adjustable storage system includes a plurality of adjustable storage receptacles, each of which may include a housing, an opening/closing mechanism, and an expansion mechanism. The expansion mechanism may be operable to increase or decrease an interior storage volume of the associated storage receptacle, enabling greater flexibility in storing objects of different shapes and sizes, relative to a fixed-size or fixed-geometry storage receptacle. In additional aspects, a method of using an adjustable storage receptacle and a method of using an adjustable storage system are provided, and further, a method of manufacturing an adjustable storage receptacle and a method of manufacturing an adjustable storage system are provided.

According to one embodiment, a vaporizing system comprises first and second tanks that can accumulate liquid source and first, second, and third pipes. The first pipe allows first gas to be sent out of the first tank. The second pipe allows second gas to be sent out of the second tank. The third pipe is connected to the first and second pipes and allows the first and second gas to be sent out to an external apparatus. The first tank is placed on an upper side of the second tank in a stacked manner.

A locking device for containers on a vehicle chassis, having a housing, a plug-in pin which is mounted displaceably in the housing and/or a rotary pin which is mounted rotatably in the housing, wherein the plug-in pin and/or the rotary pin can be moved between an open position and a locked position. The invention was based on the problem of providing a locking device for containers which is triggered automatically by way of the loading operation. According to the invention, the problem is solved by the fact that a spring element which interacts with a triggering element acts on the plug-in pin or the rotary pin, wherein the triggering unit has at least one sensing bolt which protrudes out of the housing in the direction of a container fitting in the open position.

A tank and closure cap apparatus is disclosed. The tank has an upper end or top with a manhole like larger diameter opening that can be closed with a lid having a smaller diameter opening equipped with an outlet fitting. A specially configured shroud protectively covers the lid clamp and is secured with a closure cap that seals the outlet fitting.
